I am all for it if they are the tankers
Since the friendlies trick are gone, there are less friendlies being played.
What about those that "invest" into the game - the big token buyers who buy the daily players or the events exclusive offers of 8* players?
Some of them will use more tokens via the personal trainer option to make them 9* players
Not to mention the hard training methods to expedite the players levels
I sincerely hope you do not lump the token buyers/"investors" players as mutants in your books.
Cheers
